I put frozen bread in the toaster but my hands were soaking wet. will this create mould in the toaster or on the bread? i made sure toasted fully

Mold is like a plant: Mold is like a plant. It can grow from a spore (seed), and under the right conditions becomes bigger and bigger. Think of mold as mushrooms growing in the back yard. That means mold is not "created" from nothing, but rather grown from spores. The spores are everywhere in the world. In a toaster, the high heat cooks the spores (and dries the inside of the machine) so that mold does not grow there.
